OP CON Solid Aluminum Capacitor SES & SEL Series
Skywell`s OP-CON is aluminum solid electrolytic capacitor that uses organic semiconductors as electrolytes.
Organic semiconductor has a high conductivity and high-temperature stability, therefore OP-CON has an excellent
performance and high reliability. The constructions of OP-CON are roughly the same as an aluminum electrolytic
capacitor.
